I really got into the early re running of the Teen Titans which started with writer Geoff Johns way back when it came out around the same time as the cartoon series. It was just an all around good running of a comic book series that needed a decent follow up after the Judas Contract story arc. Good stuff but I lost interest after Superboy was killed, there was the Cassandra/Batgirl turned heel and joining up with Deathstroke to defeat the Titans, but it just didn't hold my interest the same as the build up to the inifite crisis did. So I pretty much dropped reading it after that.
Started up on Sonic the Hedgehog comics, they are at least trying to get something going where Tails and Sonic are enemies not sure how it will play out in the end, the writer said it will be in there for at least three issues building up from issue 176 which comes out next month.
